In addition, when designing the touch screen circuit principle, the grounding of the FPC cable can be increased, or the touch screen cable can be covered with double-sided black electromagnetic film, which can also reduce the electromagnetic interference problem of the touch screen in practical applications. Shenzhen Hongjia Technology has been professionally developing and producing 1.14-inch to 10.1-inch displays and supporting touch screens for 12 years. It has a R&D team of more than 20 people who are familiar with solving common problems in the industry and can reduce troubles for customers.

Polarizer is one of the important materials of liquid crystal display. It is a composite material made of polyvinyl alcohol (PVA) stretched film and cellulose acetate film (TAC) through multiple lamination, stretching, coating and other processes. , can realize liquid crystal display high brightness, high contrast characteristics. Polarizers account for about 10% of the cost of TFT-LCD (Thin Film Transistor Liquid Crystal Display) panels.

Some customers are still not very clear about the resolution of the display screen. We will explain it here. The resolution of the LCD screen refers to the number of pixels of the LCD screen, that is, the number of dot matrix, which is usually the number of pixels in the horizontal direction multiplied by the number of pixels in the vertical direction. Under the same LCD screen size, the higher the resolution dot matrix, the clearer and more delicate the display image effect is.

Shenzhen Hongjia Technology specializes in the research and development, production and sales of 1.14-inch to 10.1-inch display screens and matching touch screens. There are many standard models and customization is accepted. The touch screens produced by our company have high reliability, good anti-static performance, anti-fingerprint, anti-scratch, high surface hardness and many other advantages. They are widely used in medical, military, instrumentation and other products. Customers with needs are welcome to email us for consultation.

TFT liquid crystal display screen is a display screen widely used in various electronic devices, with high resolution, high brightness, and high contrast. With the continuous development of technology, the application of wide color gamut technology is becoming increasingly widespread, which can greatly improve the display effect of display screens and make them present more realistic colors.

As the name suggests, the liquid crystal display (LCD) panel uses a liquid crystal to turn pixels on and off to display specific colors.
